IMPROVEMENT IN WIND-ENGINES.

Specification forming part of Letters Patent No; 221,788, dated November 18, 1679; application filed September 12, 1879.

To all whom it man! concern:

Beit known that I, MONTROVILLE D. CUM- MINs, of Hope, in the county of Franklin and State of Ohio, have invented anew and valuable Improvement in Wind -Engines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 is a vertical sectional view of my improved wind-engine. Fig. 2 is a face view of the wheel, and Figs. 3, 4, and 5 are details.

This invention has relation to improvements in wind-engines.

The nature of the invention will be hereinafter fully set forth.

In the annexed drawings, the letter A designates the tower, having at its upper end the cap 1), depending from which is a conical tubular depression, B, in which the spindle O of the turntable has its bearings. This spindle is tubular, and rests'or bears at its lower end against a shoulder, to, its upper bearing being in an annular collar, a, formed inside of the said conical tube at its upper end. It extends considerably above the cap of the tower, and has secured to it, at right angles, the tube D, the bore of the spindle and of the said tube communicating by a narrow opening or orifice. The tube D affords a bearin g to the main shaft 1), and the tubularplunger rod G reciprocates 'in the tubular spindle U, the main shaft and plunger-rod being in contact, so that an oil-cup in tube D will lubricate both the main shaft and rod through the orifice b.

The main shaft is provided with a crankwheel, 0, and motion endwise is given to the plunger-rod by a pitman, (1. Upon the end of the main shaft is secured the wind-wheel D, the weight of which, as well as of the overhanging parts of the turn-t able, is counterbalanced by a metallic rod, E, having a weight, w, on its end.

The tubular bearing of the main shaft is supported from the spindle by means of a bracket, brace, or other equivalent device, d.

The wind-wheel D is composed of a hub or spider, g, to which are secured in any suitable manner the radial spokes h. These spokes are braced together by a ring, f, and upon them are arranged the wind-blades I, so as to rotate freely thereon. The blades are each provided with two or more long projecting eyes, j, that receive the spokes, and, being set off from said spokes thereby, will swing out of the wind automatically under the influence of centrifugal force, thus dispensing with the use of governors. After being thrown out of the wind, at any decrease in the force of the gale, the blades will be thrown more or less into the wind by means of coiled or other springs 2', secured at one end to the spokes of the wheel, and at the other to the heal-in g of the blade. This spring is covered in by a casing, 70, and is thereby protected from being clogged by ice and snow.

The plunger-rod is tubular, as shown, and through it extends a metallic rod, J, having an arched upper end, 1, the extremity of which is pivoted to a vertically-vibrating angular le ver, H, having its fulcrum in an upright, m, on the tubular bearing of the main shaft. The weight end of this lever is forked and straddles the said tubular bearing. It works in connection with a loose, sliding collar, 00, on said bearin g, which collar is provided with angular arms or rods n extending through the hub of the wheel, and having their free ends connected with an arm, 0, projecting from the sleeves p, arranged on two or more of the spokes by means of the pivoted links q. The outer ends of these sleeves are provided with an angular arm, 1', one end of which is in engagement or contact with theinner bearingeyes of the contiguous wind-blades. By drawing down upon rod-J the collar is thrust forward toward the wheel, the angular rods thrust through the hub, the sleeves rotated upon the spokes, and the wind-blades, which are connected by the pivoted rods r, thrown out of the wind. During this movement, which is carried out from the ground, the springs are wound up, and by their reactioirthrow the blades back into the wind the moment the rod J is let go.

The windblades are made of sheet metal andprovided withapioperstitfening-rim. The spokes are preferably made of gas-pipe, and all the working parts of the engine of iron or steel.

Theouter bearingof the wind blades extends slightly beyond the end of the spoke, and the latter is inside-threaded to receive a set-screw, u, having a large head that prevents the said blade from blowing off. It also serves to adjust the blade upon the spoke and prevent rattling.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a tower having the cap I) and conical tubular extension B, provided with shoulder a and collar 11, of a turn-table, having a tapering spindle, C, substantially as specified.

2. The combination, with the tubular spindle U,the bearing-tube D,and an orifice, b, connecting the two, of the main shaft 1) in the said tube, and the plunger-rod G in the spindle, and in contact with each other, substantially as specified.

3. The combination, with a wind-wheel having the spokes I1, the connected blades 1 rotating thereon, and the springs i, of the sleeves 2 having arms 0 and r, the loose collar .1- having angular arms n extending through the hub of the wheel, the links q connecting said arms 1* and n, and the returning-springs a, substantially as specified.

4. The combination, with the spokes of a wind-wheel, of the wind-blades controlled by a spring or springs, protected by the boxing k, and having long projecting edges or bearings to receive said spokes, whereby the said blades are swung out of and into the wind without governors, substantially as shown and described.

5. The combination, with a wind-wheel havin g vibrating blades I, the sliding collar av, and a lever mechanism connecting the blades and collar, of the angular lever H, the tubular plunger-rod G, and the rod J extending down the plunger-rod, having the arched upper end and secured to said lever, substantially as set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
